B. Set Proper Comb Height

1. Loosen both of the Torx comb screws with the provided Torx tool. (Figure 7)

2. Raise or lower the comb set screws with your 5/64” Allen wrench. (Figure 8)

Note: We have provided different lengths offset screws with your stock. The comb height you require will determine which set screw length you should use.

3. Retighten both of the Torx comb screws after proper comb height has been set. (If you do not have enough range of comb adjustment see Section G Split Ring Up -Split Ring Down.)

Note: When tightening , do not force. Make Sure there is no binding or resistance.

4. Fully compress the absorber unit and check to ensure that the comb and it's supports do not touch the grip when bottomed out.

C. Set Comb Cast Off/Cast On.

1. Remove Torx comb screws to remove comb. This will allow access to cast off/cast on spacers. (Figure 9)

2. Loosen both pinch screws in the comb mounting split ring. (See Arrows Figure 9) This will allow the cast off/cast on slotted spacer to be screwed in or out.

3. Adjust spacer to desired position.

Note: There are 4 different lengths of black pinch screws (3/8, 1/2",5/8" & 3/4"). if the spacer was screwed all the way in, i.e. flush with the split ring,

you would use the 3/8" screw, 1/8 to 1/4" away from split ring (use l/2"screw), 1/4 to 3/8 or more away from split ring use 5/8" screw" 3/8 or more away from split ring use 3/4" screw.

4. Spacers must be adjusted so they are both the same.Measure with a ruler. (Figure 9)

5. Reinstall comb. Tighten Torx comb screws accordingly. Mount the gun andcheck for fit. Are you looking down the center of the rib? Don't rush thisadjustment. Fit for comfort and ease of mount.

7. Fully compress the absorber unit and check to ensure that the comb and it'ssupports do not touch the grip when bottomed out.

D. Set Comb Rotation and Position

1. Loosen all four pinch screws on comb mounting split ring.(Figure 10)

2. Comb can rotate left or right, and/or, slide forward or back to center the comb onyour face. (see Arrows Figure 10)

3. Tighten all four pinch screws.

4. Check all screws to insure they are all tightened.

5. Fully compress the absorber unit and check to ensure that the comb and it'ssupports do not touch the grip when bottomed out..

E. Adjust Butt Pad Positioning

1. Remove butt pad screws with provided 5/32 Allen wrench. This willexpose adjustment mechanism. (Figure 11).

2. Using the provided 1/8" Allen wrench loosen the flat head screws that lock thebutt pad position. Adjust pad to the position of choice. The screws may be moved from slot to slot to enable a greater range of vertical travel. Retighten the flat head screws. (Figure 12)

F. Adjusting the Felt Recoil Mechanism.

Note: This adjustment controls the pressure required to compress the absorber unit. Youmay set it very soft or stiff according to your individual preference. We preset the recoil setting to completely solid like a wood stock and then back it off 10 complete turns. This is a good starting point for most people. Shoot the shotgun then make final adjustments.Note: If absorber is set too soft the gun will move and will jump around. The stiffer theabsorber is set the less movement you will have, but will still reduce felt recoil.

1. Remove butt pad adjustment unit by removing both socket head screws from the counter bored holes in the base assembly with the 5/32" Allen wrenchprovided in your tool kit. (Figure 13)* (Note: you do not change the adjustment of your butt pad when removing it this way.)

Figure 14

Note: increase tension byturning the wrench clockwiseor turn Counter clockwiseto decrease tension. This is a very sensitive adjustment and should be done in small increments. Turn the wrench no more than 2 to3 complete turns between trials. When done adjusting, reassemble and try it out. Somewhere between very soft and stiff there is an area that

2. With the butt pad unit removed, insert the 3/16 tool into the Allen wrench socket [ldent. 13] located in the hole in the lower tube absorber unit. (Figure 14)

will maximize the reduction of felt recoil for you. When the tension is correct, if the gun is fired the barrel tip will come straight back with almost no vertical lift. Do NotRemove the Adjustment Screw From Mechanism. This could damage the unit and will

require non-warranty factory repair.

3. Reinstall butt pad adjustment unit.

G. *Split Ring Up - Split Ring Down (Helps You Obtain Correct Comb Height)(Maximize & Minimize Comb Height Adjustment)

See (Figure 15) Left Unit Ring Up - Right Unit Ring Down

Whether the rings are in the up or down position is normally determined by the ribheight on your particular shotgun. There are exceptions to these norms and the following instructions will explain how to change the rings if required.

1. Remove the comb.

2. Remove the stock assembly (absorber unit) from the grip.

Page 11

Figure 16

3. Loosen the jam set screw thatlocks the upper rod with the 1/8" allen wrench onthe newer models. (Figure 16)

4. Unscrew the upper rod with your fingers. (Figure 17)

5. Measure and record the position of the rear cast off/on spacer. (Figure 18) See Arrows.

6. Remove the aligner bracket.

7. Untighten all four split rings pinch screws. Slide the split ring off the upper rear tube. Keeping the cast off spacer tops facing you, then turn the split ring over 180 degrees. Then reinstall the ring in the desired position. (Figure 15)

8. Reassemble the mechanism inreverse order.

4. Point of Impact Adjustment(Tweaking it in / Fine Tuning)

A. Making the shotgun shoot where you are looking. This is a huge part of the game.

B. * Lowering or raising the comb will effect point of impact (center of pattern placement). Onecomplete turn of the comb set screws (see Figure 8) raises or lowers the comb 1/32". This raises or lowers the center of the pattern approximately I" at forty (40) yards. Don't just takefor granted the shotgun is shooting where you are looking. When you break a target, watch the clay target pieces. If the pieces initially go up, you're shooting under the target.

Conversely if the pieces go (blow) down, you're shooting slightly over the clay target. When you "smoke" a clay target you are utilizing the center of your pattern. When your point of impact is optimized you will "smoke" more targets as opposed to chipping them. This procedure takes time but once you have the shotgun shooting where you are looking you are on your way to more consistent and better scores regardless of weather conditions. Once you've established your correct point of impact and proper fit, additional changes should be carefully considered, and if pursued, done in small increments. Once you have something that works well for you, concentrate on relaxation and shooting one target at a time.

7. Safety: Please Read This Section Thoroughly!

A. Always check all screws for tightness after any and all adjustments.

B. Keep all your body parts out of mechanism when shooting. The grip closes toward the absorber unit and comb with a fair force (the recoil energy of the gun). Anything caught between them will be pinched hard. Keep your fingers, palm, cheek etc. out of the pinch area.

C. After any adjustments, fully compress the absorber unit and check to ensure thatthe comb and it's supports do not touch the grip when bottomed out. Note: This condition could occur when length of pull is being shortened or the comb is beingrotated or moved forward. Rotate or move the comb accordingly and readjust length

of pull to obtain clearance. Clearance at full compression between the grip and the comb and it's supports must be maintained.

D. Safety on and off the line should always be an important part of your shooting.

8. Tech Stuff...Answers to Common Questions.

A. What’s Inside?

What is inside are several hundred "belleville" washers. A "belleville" is a washer with a slight dish (cone) shape to it, made of spring steel. DO NOT REMOVE THESE FOR ANY REASON!

B. How does it "absorb" recoil?

The bellevilles when nested together, slide slightly against each other when compressed. The friction of this sliding causes heat to be generated, taking energy out of the system and your shoulder. Tech types call this loss "hysteresis". The felt recoil reduction is unaffected by temperature changes.

C. Why do I have to adjust it?

Many things effect the way you take recoil: the weight of the gun, the center of gravity, the drop at the toe, the weight of shot, the size of the powder charge, the speed of the powder, and the choke. These start an incomplete list of "hardware only" things that significantly effect felt recoil. Then there are the factors of the body behind and (hopefully) in control of the gun: weight, build, height, stance, how tightly muscled, how tense, gun mount, how tightly pulled into the shoulder, cheek position, firing technique, clothing, ..... this list goes on and on. To shorten an already long story, ONE SIZE DOES NOT FIT ALL. Properly set up the gun recoils virtually straight back with minimal muzzle climb. But... you do have to adjust it to your gun, your load, and yourself.

D. Can I Go To Soft?

Yes. If the motion in your hands is distracting or uncomfortable, then it is not stiff enough. If the absorber unit bottoms out when you shoot, it's too soft. We designed the unit with more travel than most people could possibly get used to. As you set tension in the stock and get used to it you should find your personal area of maximum comfortable felt recoil reduction. Watch your barrel, or have a friend watch your barrel when you shoot. Your barrel should come straight back horizontally with little or no vertical muzzle jump. If your barrel is bouncing or jumping and your mechanism is adjusted too soft. Try increasing the tension in the recoil mechanism by 2 or 3 turns and try it again. Tune the mechanism to yourparticular style.

Page 14

E. How Much Recoil Does It Absorb?

It depends on how you set it up for yourself, but we believe it can reduce felt recoil by 50% or greater when adjusted and fit properly.

F. What About Maintenance?

The stock is made of composite plastic, anodized aircraft grade aluminum, and stainless steel. The newer models have brassy colored bushings and require a small amount of synthetic oil occasionally.

9. Locknut / Recoil Reduction Device

You will find a 1/2" long stainless steel or black socket set screw & ball bearing in your tool kit. We refer to this as a locknut. It is 1/2" long and is threaded on the exterior. This unit and the ball bearing go into the same hole where you make the adjustment on the recoil tension ... Screw the locknut into the same hole until it touches the adjuster. This acts like a stop and keeps the recoil adjuster from changing its setting once you have it adjusted. If you have to readjust the device at some later date the locknut that you installed may be a little tight when you try and remove it (you must remove it prior to changing the adjustment) but it will come loose with a little coaxing. Remove it completely and then readjust the recoil reduction device as required.

10. Pitch Spacers

There are two (2) Pitch Spacers provided with your PFS. These are tapered wedges (thick at one end and thinner at the other). These can be used under the butt pad to adjust the pitch of the shotgun. If the spacer is installed with the thick portion toward the top of the butt pad, you would be adding down-pitch and if it were thin at the top, it would be up-pitch. When you are considering a pitch change, what you are trying to do is match the angle of the butt pad to the angle of your shoulder "when you have the gun mounted". Proper "pitch" can stabilize muzzle jump and further enhance felt recoil reduction. These spacers will have to be ground to fit the butt pad. When installed correctly the shotgun will feel very solid up against your shoulder.
